Patent GB-755528-A (GB)
Title: Improved dehydrogenation process
Inventor: STEELMAN SANFORD LEWIS
IPC: C07C5/46
Filed: 1953-10-21
Abstract: A process for the dehydrogenation of terpenetype compounds comprises mixing terpenes and sulphur with an inert hydrocarbon diluent and heating the mixture to a dehydrogenation temperature, preferably between 185 DEG  and 190 DEG  C.  The terpene-type compounds are preferably those which yield guaiazulene upon dehydrogenation such as guaiol, guaiene, partheniol, aromadendrene ledol, ledene and a -gurjunene.  The hydrocarbon diluent is preferably used in an amount of approximately twice that of the terpene.  In typical examples, guaiac wood oil or guaiene, paraffin wax and sulphur are heated for 1-1 1/2 hours under a slight vacuum until all the sulphuretted hydrogen is evolved.  The resulting guaiazulene is then distilled off and may be purified further.

Abstract: 262,438. Gurlt, Ges., W. Dec. 2, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Intercommunication systems.- The stations of an intercommunication system are each provided with a test relay which remains inert if a wanted station is engaged but energizes and locks over a local circuit to close the talking circuit, if a wanted station is idle. In the arrangement shown, when a calling party at substation I removes his receiver, presses his calling switch 34, and moves his selector 1, 2 to its second position to call substation II, the switch-hook springs 27, 91 move to the position shown and if station II is idle a test circuit is closed for relay 24 from the battery lead 20 over windings 55, 54, selector arm 1, conductors 16, 74 and choke or resistance 22 at the called station to battery lead 19. The test relay 24 locks up over its winding 53, short-circuits its high-resistance winding 55, and closes a ringing circuit 81, 27, 37, 44, 2, 75 for the bell 69 at the wanted station; as the receiver 63 is connected across resistance 37 an indication will be received at the calling station. When the called party removes his receiver, the talking circuit is completed over armatures 43, 44 of the test relay 24, the speaking wires 15, 16, and the leads 74, 75, microphone current being obtained from local batteries or from the battery leads 19, 20. If desired the spring-group associated with the calling switch 34 may be arranged, as shown at station III, to hold the talking circuit open as long as this switch is operated. If a party attempts to call a busy station no circuit is completed for his test relay, the circuit of which is opened at the switch-hook contacts 27 of the wanted station; no ringing indication is therefore received. To prevent a station from listening in to another conversation by moving his selector after the test relay has locked up, contacts 94 in the locking circuit are arranged to be opened each time the selector is moved from one position to the next. A privileged station, such as the station III, can cut into a conversation by removing his receiver, setting his selector, and depressing a key 90 which closes a locking circuit for the test relay.

Abstract: 839,008. Automatic electric transmission control. GENERAL ELECTRIC CO. Ltd. Oct. 4, 1957 [Oct. 5, 1956], No. 30482/56. Class 38 (4). In an electric driving system comprising one or more D.C. motors and one or more D.C. generators in a single closed loop, the speeds of the motors are retroactively controlled by carying their excitation in dependence upon the speed deviation from the desired value, and the current in the loop is maintained constant. The armatures of driving motors PM, SM are connected in a closed loop with the armatures of generators G1-G4 the fields of the latter being energized by an exciter E to maintain the loop current constant and the fields of the former being energized through a pilot exciter PE1 and a main exciter EM1 in accordance with the difference between a reference voltage predetermined by the setting of controllers PC and SC and the output of a tachometer generator TP. Fields EF1, EF2 which act in opposition are energized from the controllers PC, SC, and a series-connected shunt C, respectively, the output from the controllers being determined by rectifiers PX and SX to meet the requirements of the motor making the higher demand. Rectifier X2 between the exciter and reference lines permits the energizing of winding PF3 on the pilot exciter PE1 to weaken the field of motor PM whereby the loop current demanded is reduced and overload of the generators is prevented. The tachometer TP and reference voltage CV energize separate opposing fields PF2, PF1 of the pilot exciter but the two voltages may alternatively be opposed and applied to a single field. Connection of the generator field windings to the exciter E is controlled by tachometer generators TG1-TG4 coupled to the generator shafts which are driven by prime movers not shown. Wattmeters W are provided to indicate the motorload. The fields of the pilot exciters PE1, PE2 and the generator exciter E are arranged to provide full excitation in response to small differences in the strengths of the opposed fields.

Abstract: 443,255. Propelling by water-jets; toy boats. COLVER, R., 29, Whiteley Wood Road, Sheffield. Oct. 25, 1934, No. 30572. [Class 114] [See also Group XV] In arrangements for propelling ships and boats and in particular toy-craft in which steam generated in a boiler expels water from a propeller-pipe facing aft, the boiler comprises two concentric drums 7, 8 and the steam generated by the burner 21 in the narrow space between the drums expels water through the exit 20 of the pipe 19. At the end of the outward movement of the water, owing to its inertia and to the steam coming into contact with cooler surfaces, a reduction in pressure takes place and when pressure has been almost reduced to atmospheric, a previously-closed valve 16 opens to relieve residual pressure in the boiler. After the resulting backward surge of the water, steam is rapidly cooled and the valve 16 closes. In a modification, the burner plays on water tubes arranged across the inner boiler shell.
